As runners, we spend a surprising amount of time thinking about our feet, but not always in the most useful way. We compare running shoes, debate cushioning and heel drop, and try to work out whether we are pronators or supinators, often based on how our shoes wear down or what a quick gait scan tells us. What we rarely consider, is why our feet move the way they do in the first place, or whether they are even able to move as they should. Before blaming our mechanics or reaching for a different pair of shoes, it is worth asking a more basic question. Are our ankles doing their job properly?
When it comes to mobility and strength work, most runners look further up the body. We focus on our knees and hips. Calves get stretched when they feel tight. Hamstrings are usually high on the list, especially if someone has been told they are weak or stiff.
The ankle, though, is often forgotten, despite being the joint that absorbs a huge amount of force with every single step you take. Ankle mobility for runners matters far more than many people realise, because every stride you run depends on how well your ankle moves, loads, and transfers force through the rest of your body.
Ankles Rarely Make the Priority List
Part of the reason ankles are ignored is that they are easy to take for granted. As long as they are not painful, they tend to be left alone.
Another reason is that ankle mobility sounds simple, almost too basic to be important, especially when compared to topics like hip stability or running economy. Many runners also assume that stretching their calves covers ankle mobility, so they tick that box and move on.
The problem is that ankle mobility is not just about flexibility. It is about how well the joint moves under load, how easily your lower leg can travel forward over your foot, and how smoothly your body can absorb impact before pushing off again.
When ankle movement is limited, the body does not stop running. It simply finds another way to keep moving, and those compensations usually show up somewhere else.
How the Ankle Works
Simply put the ankle is the joint that connects the lower leg to the foot. It acts as a hinge that allows your body to move forward over your foot.
The most important movement for runners is the ability of the ankle to bend upward as your foot is on the ground, (dorsiflexion), which allows your shin to move forward smoothly during each step.
This movement helps absorb force when you land and sets you up for an efficient push off. Alongside this, the ankle and foot need to be able to make small adjustments side to side so you can stay balanced on uneven ground and adapt to changes in surface. Muscles and tendons around the ankle control these movements and help store and release energy as you run.
When everything moves well, this all happens automatically and efficiently. When dorsiflexion is restricted, the system still works, but not as smoothly as it could.
What Limited Ankle Mobility Can Look Like
When we talk about ankle mobility in runners, what we are really talking about most of the time is dorsiflexion. It might sound like a small movement, but it is one of the most important actions your ankle performs every time you run.
When there is good dorsiflexion available, the ankle does its share of the work, which takes pressure off the calves, knees, and hips. When dorsiflexion is limited, the body has to find another way to keep moving forward, often by lifting the heel early, overworking the calves, or shifting load up the chain.
Many of the signs runners attribute to tight calves or poor flexibility are actually signs of restricted dorsiflexion. Constant calf tightness that never seems to resolve, difficulty keeping the heels down during squats, or struggling to get the heels anywhere near the floor in downward dog are all common indicators. Plantar fascia discomfort and Achilles irritation can also be linked to limited dorsiflexion, as the tissues are forced to absorb load without enough movement at the ankle.
Dorsiflexion also plays a key role in running efficiency. When your ankle cannot move far enough into this upward bend, your stride often shortens and feels heavier. You may feel like you are working harder at the same pace, particularly on hills or when running downhill. Improving dorsiflexion can make running feel smoother even without changes to fitness or training volume.
Reasons We Lose Ankle Mobility
Ankle mobility doesn’t disappears overnight. It tends to fade gradually, shaped by how we train and how we live. Running itself is repetitive, and while repetition is part of what builds fitness, it can also lead to stiffness if movement variety is lacking. Calf muscles and the Achilles tendon work hard during running, and without enough recovery and mobility work, they can gradually lose elasticity.
Previous ankle injuries are another big factor. Even a mild sprain can change how the ankle moves if it is not fully rehabilitated. Swelling, scar tissue, and protective movement patterns can all limit motion long after the initial injury has settled. Many runners return to training once pain is gone, but never quite restore normal movement.
Daily habits also play a role. Long periods of sitting, limited barefoot time, and wearing stiff or supportive shoes all day can reduce the amount of natural movement the ankle gets. Over time, the joint adapts to this reduced demand by becoming less mobile.
There is also a strength element. If the muscles that control ankle movement are weak or poorly coordinated, the nervous system may restrict movement as a protective strategy. In that case, the ankle feels tight even if the tissues themselves are not especially short.
Checking Your Ankle Mobility
You do not need fancy equipment or a professional assessment to get a sense of whether your ankle mobility might be limited. A few simple checks can give you useful clues.
One of the easiest tests is the knee to wall test. Stand facing a wall with your toes a few inches away and your heel flat on the ground. Slowly bend your knee and try to touch the wall without your heel lifting. If you cannot reach the wall without the heel coming up, or if one side feels much tighter than the other, that is a strong sign your ankle mobility is restricted.
Another useful check is a bodyweight squat. Squat down as comfortably as you can and notice what happens at your feet and ankles. If your heels lift early, your feet turn out excessively, or you feel blocked at the front of the ankle, limited mobility may be influencing your movement.
You can also pay attention during everyday movement. If going down stairs feels awkward, if your calves always feel tight despite stretching, or if one ankle consistently feels stiffer when warming up for a run, these are often signs that ankle movement is not as free as it could be.
Simple Methods to Improve Ankle Mobility & Dorsiflexion
Improving ankle mobility does not need to be time consuming or complicated. A handful of simple exercises done regularly is usually enough to make a noticeable difference. The focus is on restoring movement, building control, and getting the ankle comfortable moving through the ranges it needs for running.
- Ankle circles
Sitting or standing, slowly move your ankle through large circles in both directions. Keep the movement controlled and smooth rather than rushing. This helps restore basic joint movement and awareness. - Slow calf raises on a step
Stand on a step, rise up onto your toes, then slowly lower your heels down below the edge. Focus on a slow, controlled lowering phase. This improves strength while encouraging the ankle to move into dorsiflexion. - Calf stretches with straight and bent knee
A straight back leg targets the larger calf muscle, while a slightly bent knee targets the deeper calf muscle closer to the ankle. Hold each stretch comfortably and breathe, rather than pushing aggressively. - Toe raises (shin strengthening)
With your heels on the floor, lift the front of your feet toward your shins, then lower slowly. This strengthens the muscles that help lift the foot and control ankle movement during running. - Knee to wall ankle mobility drill
Standing facing a wall, gently move your knee forward over your toes while keeping your heel on the ground. Only move as far as you can without forcing it. This trains ankle movement in a position that closely matches running mechanics.
A few minutes of these exercises, added to a warm up or cool down several times per week, is usually enough to start restoring better ankle movement and control.
Don't Neglect Your Ankle Mobility
The good news is that improving ankle mobility does not require long stretching sessions or adding another demanding workout to your week. Simple exercises like ankle circles, toe raises, or gentle mobility drills can easily be done while you are sitting at your desk, watching television, or winding down in the evening. Even a few basic stretches performed regularly can help restore movement and improve dorsiflexion of the ankle and, in turn, improve how your body moves with each running stride.
When ankle mobility improves, running mechanics often improve with it. Stride can feel smoother, impact better absorbed, and compensations further up the body may start to ease. So do not forget about your ankles. Give them a little consistent attention and they will often repay you by loosening up those calves, taking pressure off tired legs, and helping your running feel easier and more comfortable over time.
